| 摘要 |
A method for producing an annealing separator coating on grain oriented silicon steel prior to final texture annealing to improve the coating uniformity and prevent oxidation of the steel surface during this annealing operation. The method comprises coating the steel with a conventional coating, such as magnesium oxide, having an addition of an inert, high temperature refractory annealing separator agent, preferably calcined alumina. An annealing separator composition is also provided.
